TO ALL WIIOM IT MAY CONCERN:

Bo it known that we, NATHAN DEWEY and Guoneu W. FosDIcK, ot Dowagiac, in the county of Cass, and in the State of Michigan, have invented n. new and useful Improvement in Water-Wheels ;A and we ilo-hereby declare that .the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon'.

In the annexed drawing, making part of this specification, A represents a horizontal water-wheel, which is We use two rim-wheels, B and C, which are cast of sufficient depth, andthe one, B, being made as follows: v y

than the otheras it is desired that the width of the buckets should be. These runde as much less in diameter wheels B and C are concentric and have a common axle orshaft E, which is connected to the inner wheelb a i v f y means of the arms F F. G' and D represent the buckets of this water-wheel A, and in this' instance are eight in number of each kindf The bucketsG are intended to receive the direct action of the water, and are made nearly4 L-shapcd, with'one ring standing vertically and the other horizontally, or nearly so, the water being v received on the angular side, :1nd exerting its pcrcussivc power-.against thevcrtical side inainly. D representsv thc other series of buckets, which lie immediately beneath the buckets G, in an inclined position, and receive the force of the reaction and weight of the water. lI'he uppcr `edges e e of these buckets are flush with the upper edges ofthe rim-wheels. The buckets, as theyV incline downward, have a suitable torsion given them, so that the outer corner of the lower edge 'reaches down to the lower edge of the outer rim-wheel C, while the inner corner of this edge lics against the inner rim-wheel', about twotl1irds of its way toward its lower edge. By this torsion of the buckets the' water is discharged at or'nearstheir lower outer corners, and near the periphery of thc wheel. Il represents a scroll-chute, vwhich is made in aspiral tapering form, with two sides and top, but without bottom, and is placed. immediately over the buckets of the wheel A. The centre of this scroll is composed of a disk or plate, I, which is made just large enough to lie lupon the inner rim-wheel B,covering its internal surface. v O

The scroll is provided with a flange, J, on its outer loweredge, which rests at suitable points upon standards' for supporting the scroll, and securin'git {irrnlyin 'its place'. rIhis scroll is made of suoli size and taper that iti will supply, as nearly ns possible, the exact amount of water which the wheel will receive at each bucket.

ABuck unter does not obstruct the action ot' this wheell In settingthc wheel, its tcp is on a level withthe surface ofthe water in thctnil-rnce. We thus obtain a fall over other wheels equal to the depth of our wheel.

This wheel may be set in the bottom of the flume, and al series o'f gates, .to correspond with the number of I buckets, used for regulating and cutting 'offthe supply of water.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is- The wheel A, composed of the rims B O and their buckets, D and Gr, thebuckets D heilig curved and inclined from the upper portion of the inner rim to the lower portion of the outer rim, all constructed and operating substantially as specified.

In testimony that we claim the'foregoing, we have hereunto set our haudsthis ISthday of November, 1867.
